Getting Started

2.1 Quick Start

This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview

The VM-1610 is a high-performance distribution amplifier for balanced

stereo signals. It can also be configured as one 1:10 or two 1:5 balanced

stereo audio distribution amplifiers.

The VM-1610 features:

•Grouped audio level controls

•Configuration as a 1:10 or 2x1:5 DA

•A signal to noise ratio of 92dB @1Vpp

•A standard 1U 19” rack mount size

The VM-80A is a high-performance distribution amplifier for balanced

stereo audio signals. It can be configured as one 1:8 or two 1:4 balanced

stereo audio distribution amplifiers.

The VM-80A features:

•Grouped audio level controls

•Configuration as a 1:8 or 2x1:4 DA

•A signal to noise ratio of 100dB @1Vpp

•Compact desktop size. Two units can be rack mounted side-by-

side in a 1U rack space with the optional RK-1 adapter

To achieve the best performance:

•Use only good quality connection cables1

•Avoid interference from neighboring electrical appliances that

may adversely influence signal quality and position your Kramer

products away from moisture, excessive sunlight and dust

to avoid interference,

deterioration in signal quality due to poor matching, and elevated

noise levels (often associated with low quality cables).

5 Installing the VM-1610 in a Rack

This section describes how to install the VM-1610 in a rack.

Before Installing in a rack How to Rack Mount

Before installing in a rack, be sure that the environment is

within the recommended range: To rack-mount a machine:

1. Attach both ear brackets to the

machine. To do so, remove the

screws from each side of the

machine (3 on each side), and

replace those screws through the

ear brackets.

2. Place the ears of the machine

against the rack rails, and insert the

proper screws (not provided)

through each of the four holes in the

rack ears.

Note that:

•In some models, the front panel

may feature built-in rack ears

•Detachable rack ears can be

removed for desktop use

•Always mount the machine in the

rack before you attach any cables

or connect the machine to the

power

•If you are using a Kramer rack

adapter kit (for a machine that is not

19"), see the Rack Adapters user

manual for installation instructions

(you can download it at:

http://www.kramerelectronics.com)

Operating temperature range +5°to +45°C (41°to 113°F)

Operating humidity range 10 to 90% RHL, non-condensing

Storage temperature range -20°to +70°C (-4°to 158°F)

Storage humidity range 5 to 95% RHL, non-condensing

CAUTION

When installing on a 19" rack, avoid hazards by taking

care that:

1. It is located within the recommended environmental

conditions, as the operating ambient temperature of a

closed or multi unit rack assembly may exceed the

room ambient temperature.

2. Once rack mounted, enough air will still flow around

the machine.

3. The machine is placed straight in the correct

horizontal position.

4. You do not overload the circuit(s). When connecting

the machine to the supply circuit, overloading the

circuits might have a detrimental effect on overcurrent

protection and supply wiring. Refer to the appropriate

nameplate ratings for information. For example, for

fuse replacement, see the value printed on the

product label.

5. The machine is earthed (grounded) in a reliable way

and is connected only to an electricity socket with

grounding. Pay particular attention to situations where

electricity is supplied indirectly (when the power cord

is not plugged directly into the socket in the wall), for

example, when using an extension cable or a power

strip, and that you use only the power cord that is

supplied with the machine.

Connecting the VM-1610 and VM-80A

6 Connecting the VM-1610 and VM-80A

Section 6.1 describes how to connect the VM-1610 and section 6.2

describes how to connect VM-80A.

6.1 Connecting the VM-1610 Distribution Amplifier

To connect the VM-1610 in a 1:10 configuration, as shown in Figure 3, do

the following1

1. Connect the input source (for example, a balanced stereo audio player) to

the Channel 1 INPUT terminal block connector.

2. Connect the OUT terminal block connectors to up to 10 acceptors (for

example, balanced stereo audio recorders).

3. Release the MODE button to the 1:10 position.

4. Switch on the VM-1610.

The audio input is distributed to the audio outputs.

Note: The Channel 2 INPUT cannot be distributed to the 10 outputs,

only the Channel 1 INPUT.

5. Adjust the right and left audio levels by turning the CH1 and CH2 LEVEL

trimmers with a small screwdriver.

To connect the VM-1610 in a 2x1:5 configuration, do the following1:

1. Connect input source 1 (for example, a balanced stereo audio player) to the

Channel 1 INPUT terminal block connector.

2. Connect input source 2 (for example, a balanced stereo audio player) to the

Channel 2 INPUT terminal block connector.

3. Connect the Channel 1 OUT terminal block connectors to up to 5 acceptors

(for example, balanced stereo audio recorders).

4. Connect the Channel 2 OUT terminal block connectors to up to 5 acceptors

(for example, balanced stereo audio recorders).

5. Press in the MODE button to the 2x1:5 position.

6. Switch on the VM-1610.

The Channel 1 audio inputs are distributed to the Channel 1 audio outputs.

The Channel 2 audio inputs are distributed to the Channel 2 audio outputs.

1 Switch OFF the power on each device before connecting it to your VM-1610. After connecting your VM-1610, switch on

its power and then switch on the power on each device

6.2 Connecting the VM-80A Distribution Amplifier

To connect the VM-80A in a 1:8 configuration, as shown in Figure 4, do the

following1

1. Connect the input source (for example, a balanced stereo audio player) to

the CH 1 INPUT terminal block connector.

2. Connect the OUT terminal block connectors to up to 8 acceptors (for

example, balanced stereo audio recorders).

3. Press the 1:8 MODE button.

4. Switch on the VM-80A.

The audio input is distributed to the audio outputs.

Note: CH 2 INPUT cannot be distributed to all 8 outputs, only the CH

1 INPUT can.

1 Switch OFF the power on each device before connecting it to your VM-80A. After connecting your VM-80A, switch on its

power and then switch on the power on each device
